Inventory Calculator for Platelets

A tool to calculate the estimate of the number of platelets used, on average, daily. This is helpful for sites that find it useful to hold platelet inventory on site and estimate the number of platelet doses to keep on hand. Platelet usage can vary quite a bit, therefore, this tool is only constructed to provide a starting point or to validate existing stock inventory levels.
